The PagerDuty Post-Mortem Handbook

Lessons learned from the trenches and how you can conduct better postmortems No major incident is ever truly resolved without a postmortem. Its a way to look
back and review the incident in detail to determine exactly what went wrong, why it went wrong, and what can be done in the future to make sure it doesn't happen
again.

To that end, we'd like to share how we here at PagerDuly conduct postmortems internally. It is our hope that others will use the documentation as a starting point to formalize their own processes. This guide to pastmorterns provides information on what to do after a major incident and shares PagerDury's follow-up and after-
action review procedures.
